Cannot Type in the Arduino Programmer

[bennylaird]

Hi

I am using a PiNet classroom to program Arduino projects.

When I open the programmer I cannot enter text. Last year I solved this by reconfiguring Java but I can not recall how I did it. It was a line of code with config Java etc.

I cannot find the original reference so hoping that someone can help out.

Thanks
